}
fmt.Print("输入+ - * / 符号: ")
fmt.Scanf("%s\n", &operation)

if operation != "+" && operation != "-" && operation != "*" && operation != "/" {

return false
}

handler := counter.InputData{x,y,operation}
answer = handler.Ufunc();

fmt.Println(x,operation,y,"=",answer)
fmt.Println("您的计算结果为：",answer)
return true
}

func main() {
for {
Calculator()
   }
}

filepath:GOPATH/src/test/counter/handler.go

package counter

type InputData struct {
Num1 int
Num2 int
Operation string
}

func (i InputData) Ufunc() int  {
var Sum int
   switch i.Operation {
case "+":
Sum = i.Num2 + i.Num1
case "-":
Sum = i.Num1 - i.Num2
case "*":
Sum = i.Num1 * i.Num2
case "/":
Sum = i.Num1 / i.Num2
}
return Sum
}

尝试做验证，x 与运算符验证正常 y输入非int时第二次获取的x值貌似有问题
